In parallel, the European Medicines Agency (EMA) provided a positive opinion on Orphan Drug Designation for Lusvertikimab for the treatment of Acute Lymphoblastic Leukemia (ALL).

Nicolas Poirier, Chief Executive Officer of OSE Immunotherapeutics, comments: "After the planned DSMB review recommendation to continue the study until its completion, the Company’s primary and strategic focus remains clinical evaluation of Lusvertikimab in this ongoing ulcerative colitis Phase 2 study with end of accrual expected in the following months. In parallel, based on strong preclinical activity demonstrated by Lusvertikimab using patient’s leukemic samples, we are happy to have received a positive opinion on Orphan Drug Designation from the European Medicines Agency. Lusvertikimab orphan status for the treatment of Acute Lymphoblastic Leukemia from B or T cell precursors is opening future potential new indications in ALL, rare diseases with limited treatment options. We warmly thank our academic and clinician partners in Kiel, involved with us in this innovative research program."

ABOUT LUSVERTIKIMAB CLINICAL EVALUATION IN ULCERATIVE COLITIS (UC)

The ongoing Phase 2 clinical trial sponsored by OSE Immunotherapeutics is evaluating the efficacy and safety of Lusvertikimab (OSE-127) versus placebo in patients with moderate to severe active UC who failed or lost response or were intolerant to previous treatment(s) (CoTikiS trial: NCT04882007). A positive interim futility analysis was observed in the prespecified first 50 patients (i.e., 33% of the total patient enrollment in the study) having completed the induction phase. The upcoming major milestone for this Phase 2 clinical trial is expected in the following months with the top-line results after the induction phase (primary endpoint at week 10) and in H1 2024 for the first early assessment in maintenance after 6 months of therapy. UC is a debilitating and chronic inflammatory bowel disease which affects 3.3 million patients in US, Europe and Japan (1), representing 12.2 per 100,000 people by year (2). Despite broad available options, remission rates remain only 25-30% (3), leaving most patients without satisfactory treatments.

ABOUT THE LUSVERTIKIMAB RESEARCH PROGRAM IN ACUTE LYMPHOBLASTIC LEUKEMIA (ALL)

This collaborative research program between OSE Immunotherapeutics and the University Medical Center Schleswig-Holstein in Kiel (Germany) evaluated the therapeutic potential of Lusvertikimab in targeting and blocking the high and dysregulated IL-7R expression observed in 84% of B- or T-Cell ALL (B- and T-ALL) patients. In particular, significant preclinical activity of Lusvertikimab has been demonstrated in models using leukemic samples from refractory and relapsed patients. The latest preclinical data on the use of Lusvertikimab for the treatment of B- and T-ALL and its dual anti-leukemic efficacy were presented and awarded at the American Society of Hematology (ASH) (Free ASH Whitepaper) annual meeting in December 2022.

In Europe, 7,000 cases of ALL are diagnosed each year (1). The condition is estimated to be affecting approximately 1.7 in 10,000 persons in the European Union (2). More globally, the number of diagnosed incident cases of ALL in Europe, US, Japan and China is estimated to achieve 26,482 cases in 2029(3).

Givastomig is engineered to bind to CLDN18.2-expressing cancer cells and co-stimulatory receptor 4-1BB on adjacent T cells, with the aim of activating T cells specifically within CLDN18.2-expressing tumors and triggering a potent tumor-killing effect. This innovative approach offers the potential for effective and targeted immuno-therapy in gastric cancer, a disease characterized by a poor prognosis and limited treatment options.

Results from this study demonstrated that 4-1BB+ T cells co-exist in close proximity to CLDN18.2+ gastric cancer cells in patients. Moreover, givastomig bound to tumor cells across a wide range of CLDN18.2 expression levels and induced 4-1BB activation only in the context of CLDN18.2 binding, indicating the targeted effect of 4-1BB activation in the presence of CLDN18.2+ cells. In the in vivo CLDN18.2-expressing tumor model, givastomig induces localized immune activation in tumors, increasing the ratio of CD8+/Treg cells, resulting in superior anti-tumor activity and long-lasting memory response against tumor rechallenge.

"The findings from our research demonstrate the significant potential of givastomig in treating gastric cancer patients with varying levels of CLDN18.2 expression," said Dr. Lin Shen, Professor of Clinical Oncology at the Beijing Cancer Hospital of Peking University, and Director of SIP LifeLink Oncology Research Institute. "By activating 4-1BB signaling in a CLDN18.2 engagement-dependent manner, givastomig can avoid the risk of liver toxicity and systemic immune response commonly observed with other 4-1BB stimulating agents in previous clinical trials."

"We are excited to see this manuscript published in JITC, as it showcases the innovative design and remarkable anti-tumor activity in preclinical models of givastomig," said Dr. Andrew Zhu, President of I-Mab. "This molecule has demonstrated promising results in this study by effectively activating T cells and triggering a localized immune response within the tumor microenvironment. With ongoing clinical studies, we aim to build upon these findings and ultimately make this innovative therapy accessible to patients with gastric cancer."

Givastomig is currently undergoing Phase 1 clinical studies both in the U.S. and in China. Encouragingly, the Phase 1 study has shown favorable safety profile and promising efficacy signals thus far. The Company intends to report additional clinical data from the study at a major medical conference in the second half of the year.

About Givastomig

Givastomig, also known as TJ-CD4B/ABL111, is a Claudin 18.2 and 4-1BB bispecific antibody capable of binding to tumor cells expressing Claudin 18.2, i.e., gastric cancer and pancreatic cancer cells, and stimulating intra-tumoral T cells by the 4-1BB arm designed to be activated only upon tumor engagement while silent elsewhere. Givastomig effectively maintains a strong tumor binding property and anti-tumor activity attributable to a synergistic effect of both Claudin 18.2 antibody and 4-1BB antibody while avoiding or minimizing liver toxicity and systemic immunotoxicity commonly seen with 4-1BB antibodies as a drug class. Being developed under collaboration between I-Mab and ABL Bio, a clinical-stage biotechnology company in South Korea, givastomig is currently being investigated in a phase 1 clinical study in the U.S. and China. In March 2022, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for givastomig for the treatment of gastric cancer, including cancer of gastroesophageal junction.

On July 5, 2023 CoImmune, Inc., a clinical stage immuno-oncology company working to redefine cancer treatment using best-in-class cellular immunotherapies, reported the publication of preclinical data demonstrating that a strategy based on the company’s proprietary Chimeric Antigen Receptor-Cytokine Induced Killer (CAR-CIK) cell platform provides advantages over single-targeting CARs including improved efficacy and high specificity in a model of acute myeloid leukemia (AML) (Press release, CoImmune, JUL 5, 2023, View Source [SID1234633065]). The preclinical data are published in Blood Advances, a peer-reviewed journal of the American Society of Hematology (ASH) (Free ASH Whitepaper).

"CAR-engineered T-cells have demonstrated high therapeutic potential, but further development is required to ensure a safe and durable disease remission in AML," said Andrea Biondi, M.D., Professor of Pediatrics at the University of Milano-Bicocca and Scientific Director of the M. Tettamanti Research Center. "The impressive safety profile and encouraging activity of CAR-CIK cells is particularly attractive in the AML setting, in which older age and comorbidities hamper adoptive cell therapy options because of the risk of severe cytokine release syndrome or immune effector cell–associated neurotoxicity syndrome."

The publication, titled, "IL-3-zetakine combined with a CD33 costimulatory receptor as a dual CAR approach for safer and selective targeting of AML," describes an approach to developing CAR-CIK cells that co-express a first-generation low affinity anti-CD123 interleukin-3–zetakine (IL-3z) and an anti-CD33 as co-stimulatory receptor without activation signaling domains (CD33.CCR). The dual strategy demonstrated powerful antitumor efficacy against AML targets without any relevant toxicity on hematopoietic stem and progenitor cells (HSPCs) and endothelial cells. Specifically, the researchers found:

CD123 and/or CD33 knockout impairs leukemia growth by modulating multiple cancer pathways in a model of NPM1-mutated AML.
CAR-CIK cells mediate high antileukemic efficacy through transacting co-stimulation.
Low affinity CAR-CIK cells decrease on-target/off tumor toxicity against endothelial and HSPCs in vitro.
Low affinity CAR-CIK cells preserve antileukemic efficacy in vitro and improve antitumor control in vivo.
"CAR T-cell therapy in AML is limited by the absence of an ideal tumor-specific antigen," said Sarah Tettamanti, Ph.D., Tettamanti Center, Fondazione IRCCS San Gerardo dei Tintori, Monza, Italy. "In this study, we describe a novel strategy using CAR-CIK cells to target both CD33 and CD123 without the risk of severe on target/off-tumor toxicities. This approach has the potential to improve the outcome of patients with AML."

On July 5, 2023 10x Genomics, Inc. (Nasdaq: TXG), a leader in single cell and spatial biology, reported that its single-cell genomic technologies were used in a study published in the journal Nature Medicine about new gene signatures that explain why some children with leukemia have longer remission after CAR T-cell therapy (Press release, 10x Genomics, JUL 5, 2023, View Source [SID1234633064]). The collaborative research project was conducted by researchers from Great Ormond Street Hospital (GOSH), the Wellcome Sanger Institute and the UCL Great Ormond Street Institute of Child Health (UCL GOS ICH).

Researchers conducting the study, "Transcriptional signatures associated with persisting CD19 CAR-T cells in children with leukemia," used Chromium Single Cell Gene Expression technologies and T-cell receptor sequencing of samples to look at what makes the long-lasting CAR T-cells unique. These helped identify a genetic signature of the CAR T-cells that persisted in the body long-term – an important predictor of durable remission. The data was from the CARPALL trial, which used molecular features and clonal dynamics of CD19 CAR T-cells of 10 children with relapsed or refractory B-cell acute lymphoblastic.

Ben Hindson, Co-founder and Chief Scientific Officer at 10x Genomics, said, "Single cell genomics is a powerful tool that is transforming cancer research and our understanding of health and disease. We are so proud to have 10x technologies behind this incredible breakthrough. We celebrate the achievements of the research team and the selfless dedication of the families who made this study possible. We look forward to continuing to give researchers the technologies needed to fuel new biological discoveries and ultimately help improve patient care."

Using Chromium Single Cell Gene Expression products, researchers identified a unique double negative phenotype of long-lasting CAR T-cells, which provides insights into how these cells survive and remain active in the body. These key genes appeared to enable the CAR T-cells to persist and therefore allow the children to live cancer free long-term. The findings may lead to discovering new biomarkers that could predict the long-term durability of CAR T-cell therapies and provide better treatment options for patients.

Dr. Sam Behjati, co-senior author, Group Lead and Wellcome Senior Research Fellow at the Wellcome Sanger Institute and Honorary Consultant Paediatric Oncologist at Addenbrooke’s Hospital, Cambridge, said, "This study is a fantastic step forward in our understanding of CAR T-cell persistence and illustrates the power of collaborative science and combining pioneering clinical research with cutting-edge genomic science. It is crucial that we continue to develop and build on these new treatments to help more children with leukaemia across the world."
